Water waves are hitting a boat if the frequency water waves is reduced to 1/3 of the original frequency what happens to the energy transferred to the boat

trig 15.3 cos

what is the actual question though?

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
